State media declared the test a complete success and said no radiation had leaked into the atmosphere.

Atomic or "A-bombs" work on the principle of nuclear fission, where energy is released by splitting atoms of enriched uranium or plutonium encased in the warhead.

Hydrogen or H-bombs, also known as thermonuclear weapons, work on fusion and are far more powerful, with a nuclear blast taking place first to create the intense temperatures required.

There was no immediate independent confirmation of the North's claim. But the blast was its most powerful to date by far and many experts said it had all the hallmarks of a hydrogen bomb.
